4 Torque figures
The torque figures detail motor torque characteristics for fullstep operation in order to allow simple
comparison. The motors were positioned on rubber. The diagrams are based on discrete
measurement points of pull-out torque (torque needed to stop rotating motor). For fullstep operation
there are always a number of resonance points (with less torque) which are not depicted. These will
be minimized by microstep operation in most applications.
